2011년부터 시행된 교육과학기술부의 LINC 사업을 통해 산학협력중점교수 제도가 처음 도입된 이후, 산학협력중점교수의 수는 가파르게 증가하였고, 산학협력 활동의 매개 주체로서 산학협력중점교수가 중요한 역할을 수행하고 있는 것으로 평가되고 있다. 그러나 산학협력중점교수 제도 운영에 필요한 인건비의 70%를 LINC 사업비에 의존하고 있는 프로젝트 사업의 특성상 LINC 사업에서 중도 탈락하거나 LINC 사업이 종료된 후에도 산학협력중점교수 제도가 존속할 수 있을지 의문이 제기되고 있는 상황이다. 이에 본 연구에서는 문헌고찰을 비롯해 산학협력중점교수 제도를 운영하고 있는 대학들을 대상으로 한 설문조사 및 전문가 심층면담조사 결과를 토대로 산학협력중점교수의 실태 및 문제점을 파악하였다. 그리고 이를 바탕으로 제도 개선방안을 법 제도적, 재정적, 구조적인 측면에서 제시하였다.

This study was conducted to develop a new functional material by optimizing the conditions for high concentrations of chlorogenic acid and eleutheroside E in Acanthopanax koreanum stem. The total phenolic compound content was the highest in the 20 hours sonication Acanthopanax koreanum stem extract (UAK-20). In addition, eleutheroside E, a typical functional ingredient of Cortex Acanthopanacis, in the 20 hours treated Acanthopanax koreanum stem extract showed the highest content at 1.646%. However, another functional ingredient, chlorogenic acid, showed the highest content of 2.625% in 1 hour treated Acanthopanax koreanum stem extract. Therefore, it is considered that the optimal conditions for high concentrations of total phenolic compound and eleutheroside E are 20 hours sonication Acanthopanax koreanum stem extract.

In precision agriculture (PA), the differences of the agriculture related parameters such as temperature, humidity, soil moisture among different fields are considered and analyzed to precisely utilize water, pesticides, fertilizer, seeds, etc. in fields. Hence, it becomes possible to increase the profit, reduce waste and maintain quality products. This paper suggests a framework for RFID sensor network in view of PA, especially, associated with Container-grown seedlings(CGS), and presents the analysis and simulation by using Ultra High Frequency (UHF) RFID tag system. The simulation is divided into the transmitter and receiver part using Matlab/Simulink. The architecture of the model is flexible to achieve different modulation and encoding types. Finally, some results of the simulation are presents.

The purpose of this study was to examine the changes in seasonal bioactive components of 4 and 6 years old fresh ginseng (Panax ginseng) and to provide basic information on the development of functional food using fresh ginseng. Seasonal changes were investigated by ginseng saponin analysis using HPLC method and acidic polysaccharides by carbazole sulfuric acid method. Total saponins showed the highest content of fresh ginseng collected in May, followed by March, July, and September. Fresh ginseng collected in May showed 2.5 times (4 years old) - 3.0 times (6 years old) higher than fresh ginseng collected in September. Acidic polysaccharides showed high content of fresh ginseng collected in March and September, and low content of fresh ginseng collected in May and July. From these results, the fresh ginseng collected in May can develop high concentrations of saponin. On the other hand, fresh ginseng collected in March and September is thought to be able to develop high concentration products of acidic polysaccharides.

This study has been investigated on the durability of carbon fiber/epoxy composites (CFRP) in moisture environment. The carbon fiber/epoxy composites were modified to use the nanoparticles such as carbon nanotubes and titanium oxide. These hybrid composites were exposed to moisture environment for a certain period of time. Weight gain according to immersion time, quasi-static tensile test and micro-graphic characterization were investigated on the samples exposed to moisture environment. Consequently, the weight gains increased with increasing immersion time and weight gain of the hybrid composites was lower than the one of CFRP through the whole immersion time. The tensile strengths decreased with increasing immersion time and tensile strengths of the hybrid composites were higher than the one of CFRP through the whole immersion time. The CFRP were observed more degraded than hybrid compositess in moisture environment. Therefore, it was concluded that the addition of nanoparticles in CFRP could lead to improve the durability in moisture environment.

In this study, porcelain bonding strength and mechanical properties of sintered Ni-Cr-Ti alloy for dental prosthodontics have been researched experimentally. Mechanical and morphological characteristics of the alloys were examined by Vickers hardness test, tensile and bonding strength test, surface roughness test, field-emission scanning electron microscopy, energy dispersive X-ray spectroscopy, and X-ray diffraction. In the sintered Ni-13Cr-xTi alloys, morphology of sintered alloy showed porous matrix diffused with alloying elements of Cr and Ti, and showed dendritic structure after melting process. From the XRD results, the second phases of NiCr, $Ni_3Cr$, and $Ni_3Ti$ were formed in the case of sintered and melted Ni-13Cr-xTi alloys. The tensile strength and hardness of Ni-13Cr-xTi alloys increased, as Ti content increased. Surface roughness increased, as Ti content increased. The bonding strength between metal and porcelain of Ni-13Cr-5Ti alloy was higher than those of Ni-13Cr and Ni-13Cr-10Ti alloys
